API16C Kill and Choke Manifold
Choke manifold is necessary device to control the well kick
successfully and execute the pressure control technology on oil/gas
well in the course of drilling, as it is, the device is adopted to
execute new drilling-well’s technique of balance pressure, which
can avoid pollution of oil-layer, improve the speed of drilling and
control blowout effectively. One end of the device connects with
the side flange of BOP spool. When BOP closes, it can control the
finite pressure from casing by adjusting the choke valve’s opening,
so balanced drilling can work under minimum pressure-difference.
The choke manifold consists of choke valves, gate valves, line
pipes, fittings, pressure gauges and other components.
3. Working Principles
When the pressure inside the well rises, opening/closing the choke
valves (including manual chokes, hydraulic chokes and positive
chokes) on the choke manifold can allow the release of the fluid
inside the well so as to control casing pressure, which can be
directly blown out through the gate valve if the casing pressure is
4. Pressure Ratings
The kill manifold is available in pressure ratings of 14MPa, 21MPa,
35MPa, 70MPa and 105MPa, and also can be available upon customer
5. Operating Instructions
(1) The working pressure of all components on the choke manifold
shall be compatible with that of the BOP stack used.
(2) The choke manifold shall be installed at the place where the
operator can reach it easily. The pressure test must be performed
prior to installation and the seat test pressure shall be equal to
the rated working pressure.
(3) The line pipe shall be level and straight as much as it could.
In case of the turn of the line pipe, the 120 degree steel bent
pipe shall be used. The bore of the line pipe shall be large
(4) The pressure gauge must be installed.
(5) In winter, the choke manifold can work under a low temperature
